I installed the bourbon gem on my OSX machine some weeks ago:

gem install bourbon

Now i have problems with bourbon in a web project (gulp says "mixins not found") so I wanted to uninstall and re-install the gem. So I typed:

$ gem uninstall bourbon

Surprisingly I get the following message in the terminal:

Select gem to uninstall:
1. bourbon-4.2.6
2. bourbon-5.0.0.beta.3
3. bourbon-5.0.0.beta.4
4. All versions

Hm? It seems that there are different versions of the gem installed and doing 

bourbon install

in my project folder installs the latest beta (which lacks some SASS mixins I think). I thought when I install or update a gem that the older gems are deleted or overwritten. So how to handle this the best?

run this:

$ gem uninstall bourbon

Select 4 to uninstall all the versions. Then install the gem again using the command.

gem install bourbon -v 4.2.6

Hopefully it will help.

    When I uninstalled all the gem versions and installed bourbon again he automatically installed .v 4.2.6 AND the newest beta at once. I uninstalled the beta then. I don't understand why the machine installs both versions? – herrfischer Mar 13 '16 at 19:46
